Based on the method described in the Japanese regulation for water supply, anions were analyzed using IC I-524A (an anion analysis column for non-suppressor method).Please refer to 'Regulation for Water Supply '.Sample : 100μL each
Column : Shodex IC I-524A (4.6mmI.D. x 100mm)
Eluent : 2.0mM Phthalic acid + 1.84mM Tris(hydroxymethyl)aminomethane
+ 300mM Boric acid aq.
Flow rate : 1.2mL/min
Detector : Non-suppressed coductivity
Column temp. : 40°C
